BPMN21 — Data associations need to be revisited and their use clarified.

Data associations need to be revisited and their use clarified.

Data association should have there own visual depiction. Using the look of association is misleading as data associations have a different meaning than associations.

A data association is an edge between flow elements (data objects(ref) and data stores(ref))as such they should not cross boundaries of pools or can they? This is not clear.
It is also not clear if data objects(ref) and data stores (ref) can be drwan outside lanesets or pools.
